Hauv synthesis ntawm protein ntau , peb hom RNA yog xav tau . Thawj yog hu ua ribosomal RNA (rRNA) thiab yog siv los tsim cov ribosomes. Ribosomes yog ultramicroscopic hais ntawm rRNA thiab protein ntau qhov twg amino acids txuas rau ib leeg thaum lub sij hawm synthesis ntawm cov proteins.
Hauv qhov no, dab tsi xav tau rau kev tsim cov protein?
Lwm qhov kev xav tau loj rau protein synthesis yog tus txhais lus molecules uas lub cev "nyeem" mRNA codons. Hloov RNA (tRNA) yog ib hom RNA uas ferries qhov tsim nyog cov amino acids coj mus rau ribosome, thiab txuas txhua cov amino acid tshiab mus rau qhov kawg, tsim cov polypeptide saw ib-los-ib.
Tsis tas li ntawd, dab tsi yog 5 kauj ruam hauv kev tsim cov protein? Cov ntsiab lus hauv cov teeb no (5)
- Daim ntawv luam ntawm ib sab ntawm DNA strand yog tsim (hu ua mRNA, messenger RNA)
- mRNA txav mus rau cytoplasm, ces ribosome.
- mRNA mus dhau ribosome 3 lub hauv paus ib zaug.
- Hloov RNA (tRNA) sib tw nrog qhib DNA hauv paus.
- tRNA tso tawm cov amino acid nyob rau saum toj, uas koom nrog cov saw ntawm cov amino acids raug tsim.
Ib sab saum toj, dab tsi yog peb yam uas xav tau rau kev tsim cov protein?
Cov peb lub luag haujlwm ntawm RNA hauv protein synthesis . Messenger RNA (mRNA) yog txhais ua protein ntau los ntawm kev sib koom tes ntawm kev hloov RNA (tRNA) thiab ribosome, uas yog tsim los ntawm ntau yam cov proteins thiab ob loj ribosomal RNA (rRNA) molecules.
Dab tsi yog 7 kauj ruam ntawm kev tsim cov protein?
Xya theem ntawm Protein Synthesis
- Thaum cov cai tau nyeem tas lawm, lub teeb liab nres tau muab thiab cov protein synthesis tiav thiab cov protein mus qhov twg nws xav tau. Qhov no yog Twinkie tiag.
- m RNA muab cov lej theej tawm ntawm cov nucleus mus rau ribosomes. Cov ribosomes "nyeem" theej DNA code. Muag Kickoff - EnergyWSales Kickoff - Ene…

Qhov twg hauv qab no yuav tsum tau ntsib rau kev sib tsoo txoj kev xav ntawm cov tshuaj tiv thaiv tus nqi tuav? - Lub reacting molecules yuav tsum sib tsoo nrog ib leeg. - Cov molecules yuav tsum sib tsoo nyob rau hauv ib qho kev taw qhia uas tuaj yeem ua rau rov kho cov atoms. -Cov reacting molecules yuav tsum sib tsoo nrog lub zog txaus
Dab tsi yog qhov cuab yeej tsim nyog ua ntej kev tshawb xav ntawm tes yuav tsim tau?
Lub microscope yog tsim nyog ua ntej qhov kev xav ntawm tes yuav tsim. Peb tus kws tshawb fawb twg tau txais qhab nia rau cov pov thawj ncaj qha ua rau txoj kev xav ntawm tes? Matthias Schleiden, Theodor Schwann, thiab Rudolph Virchow peb yog txhua tus kws tshawb fawb uas tau pab txhawb txoj kev xav ntawm tes
Dab tsi yog qhov yuav tsum tau ua rau kev kawm tiav qib siab?
Kev Kawm Txuj Ci Kev Kawm Qib Siab no tuaj yeem ua tiav plaub xyoos. Cov kws tshawb fawb feem ntau muaj kev kawm tiav qib siab, xws li Master of Arts hauv Sociology. Thaum nyob hauv tsev kawm ntawv tiav, ib tus tuaj yeem xaiv tshwj xeeb hauv sociology thiab criminology, sociology thiab kev lag luam lossis kev puas siab puas ntsws
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Dab tsi yog qhov index fossil Dab tsi yog ob qhov yuav tsum tau ua ib qho index fossil?
Cov pob txha muaj txiaj ntsig zoo yuav tsum yog qhov sib txawv lossis pom tau yooj yim, muaj ntau, thiab muaj qhov dav ntawm thaj chaw faib khoom thiab muaj ntau yam luv luv los ntawm lub sijhawm. Index fossils yog lub hauv paus rau kev txhais cov ciam teb nyob rau hauv lub sij hawm geology thiab rau kev sib raug zoo ntawm strata
